Answer:

1.Vibration is the mechanical oscillations of an object about an equilibrium point.

2.Sound is caused by the simple but rapid mechanical vibrations of various elastic bodies. These when moved or struck so as to vibrate, communicate the same kind of vibrations to the auditory nerve of the ear, and are then appreciated by the mind.

3.The shortest

4.As distance from the sound source increases, the area covered by the sound waves increases.

5.Striking the metal bars of the xylophone with a stick produces a vibration.

6.Sound does not travel at all in space. False

8.The Inner Ear

These nerve endings transform the vibrations into electrical impulses that then travel along the eighth cranial nerve (auditory nerve) to the brain. The brain then interprets these signals, and this is how we hear.
